Incineration by Shiva
"Kama-Dahana (Shiva Turns Kama to Ashes)
One of the principal myths regarding Kama is that of his incineration by Shiva, the Madana-bhasma (Kama Dahana). It occurs in its most developed form in the Matsya Purana, but is also repeated with variants in the Shiva Purana and other Puranas.
In the narrative, Indra and the gods are suffering at the hands of the demon Tarakasura who cannot be defeated except by Shiva's son. Brahma advises that Parvati should seduce Shiva, since their offspring would be able to defeat Taraka. Indra assigns Kamadeva to break Shiva's meditation. To create a congenial atmosphere, Kamadeva (Madana) creates an untimely spring (akāla-vasanta). He evades Shiva's guard, Nandin, by taking the form of the fragrant southern breeze, and enters Shiva's abode.

After he awakens Shiva with a flower arrow, Shiva, furious, opens his third eye, which incinerates Madana instantaneously and he is turned into ash. However, Shiva observes Parvati and asks her how he can help her. She enjoins him to resuscitate Madana, and Shiva agrees to let Madana live but in a disembodied form; hence Kamadeva is also called Ananga (an- = without; anga = body, "bodiless"), or Atanu (a- = without; tanu = body). The spirit of love embodied by Kama is now disseminated across the cosmos: afflicting humanity with the creation of lust. Lord Shiva agrees with Mother Parvati's proposal and their union is consummated. Their son Kartikeya goes on to defeat Taraka.
Reincarnation as Krishna's son
The myth of Kamadeva's incineration is referenced in the Matsya Purana to reveal a relationship between Krishna and Kamadeva. In the narrative, Kama is reincarnated in the womb of Krishna's wife Rukmini as Pradyumna, after being burned to ashes by Shiva's anger."
